I'm exhausted! For some reason, the last couple of nights I have had real trouble getting to sleep. I haven't been tossing and turning, just lying there with the same two or three thoughts running around my head. Typically, these thoughts will be:
1. A song. Usually at least 10 years old. Usually one I don't like. Last night it was the ballad "Wild Colonial Boy", as sung by Rolf Harris.
2. A medical fact that I failed to learn during the day. Last night I spent what seemed like hours speculating on what the pressure might be in the pulmonary trunk during diastole, like this: 10? No, 15. No! 12. No, it must be 8. No! 12 is right. No, it's 30. ... and so forth.
3. An obsessive fixation on a trivial detail of a book I read when I was a child or a game of chess I may or may not once have played.
It's a real bunch of laughs let me tell you.

ooh i just did this one! pulmonary artery pressure during diastole is just a bit higher than RV pressure (to ensure pulm valve closure) at 4-12 mmHg. (RV = 2-8 diastolic). [Lilly CH3 pg 61]
If you memorized the page number you are either studying too hard or we should go to the casino together.
